SPECIFICATION formingpart of Letters Patent No. 665,390, dated January1, 1901.

Application filed August 5, 1897. serial No. 647,218. (No model.)

To all whom it may concern:

Be it known that I, JOHN WILSON BROWN, Jr., a citizen of the UnitedStates, residing in Philadelphia, Pennsylvania, have invented certainImprovementsin Registering-Pum ps, of which the following is aspecification.

The main object of my invention is to construct a measuri ng-pu mp thatwill accurately measure the liquid pumped and which need not be primed.

A further object of the invention is to provide a pump that can beaccurately and cheaply manufactured and which can be readily taken apartfor cleansing or for repairs; and a still further object of'theinvention is to so construct the pump that it can be inserted into acomparatively small opening in the barrel.

My invention is especially adapted for us in pumping molasses and syrupsand like liquids from barrels, and it is a substitute for themeasuring-faucet commonly used for this purpose.

In the accompanying drawings, Figure l is a view of my improvedmolasses-pu mp. Fig. 2 is an enlarged sectional view of the upper end ofthe pump. Fig. 3 is a sectional plan view on the line 3 3, Fig. 2. Fig.4 is a vertical sectional view of the lower portion of the pump on theline 4 4, Fig. 6. Fig. 5 is a vertical sectional view on the line 5 5,Fig. 6. Fig. 6 is a sectional view on the line 6 6, Fig. 4; and Fig. 7is a sectional view on the line 7 7, Fig. 4:-

The pump is made in three sections namely, a stem A, a head A, and apumpcasing B. The head A is secured to the upper end of the stem A andhas a tubular extension A forming the outlet-nozzle of the pump.Theheadalsocarriesthedrivingmechanism, as well as the registeringmechanism, of the pump. The pump-casing B is attached to the lower endof the tube A and contains the pn mping mechanism proper, which isconnected to the driving mechanism through a rod extending through thetube A. I make the outside of the pump-casing B concentric with thetubular stem A, so that I am enabled to reduce the amount of worknecessary in manufacturing the pump and Y make it neat in appearance.Also by having the parts concentric the diameter of the hole throughwhich the pump must pass into the barrel can be just the size of thecasing, and the pump can be readily inserted into or removed from thebarrel.

On the stem A of the pump is clamped a sleeve C, having flanges c, whichare preferably secured to the upper head of the barrel, so as to preventthe pump moving when once placed in position. On the lower portion ofthe pump-casing B are spurs c, which rest on the interior surface of thebottom edge of the barrel, so that when the sleeve C and the spurs arefixed the pump is perfectly rigid.

The upper end of the stem A is screwthreaded in the presentinstance, andthe head A is screwed upon this end of the stem, and there is a passagein the head communicating with the passage in the outlet extension A Atthe end of this extension is a valvechamber at, having a valve-seat atthe nozzle, and in the chamber is a valve E for cutting off the flow ofmolasses from the pump in order to prevent dripping after the receptacleis filled with the required amount of molasses. This valve is flush withthe mouth of the nozzle when it is closed, so that there are no exposedcavities at the outlet of the pump for the accumulation of the molasses,which would attract flies and other insects. By making the valve flush,as shown in Fig. 2, both the bottom of the valve and the nozzle can bewiped clean. The valve in the present instance has an inclined slot 6,in which rests a pin 6', projecting from the casing. The valve isprovided with a suitable handle e so that on turning the handle thevalve can be raised or lowered.

Projecting from the head A is a stud a, and on this stud is a bevelgear-wheel D, having a handle d, by which it is turned. This bevelgear-wheel meshes with the bevel-pinion D, having its lower bearing inthe head A and its upper bearing in the present instance in a plate F,mounted in a case A which in this instance contains the registeringmechanismf The axis of this pinion D is coincident with that of the tubeA, and the lower bearing is provided with a suitable 10c packing orstuffing box d. This stuffing-box upper end of the hub is a socket h,and in the pass each other and to slide.

lower end of the bevel-pinion D is a socket.

Extending from the pinion to the hub is a shaft G. This shaft in thepresent instance is square, and the sockets in the hub and in the pinionare shaped to conform to the shaft, and as the axis of the pinion iscoincident with the axis of the tube A and the hub is cocentric theretothe shaft G will be inclined or diagonal with respect to the axis of thetube. The connections are comparatively loose, so that theeccentrically-sitnated hub can be readily driven from the concentricbevel-pinion. Furthermore, the shaft is not attached to either thebevel-pinion or the hub, so that when it is desired to remove the pinionor the hub either one can be removed by simply withdrawing it from theshaft.

Sliding in the hub H are two blades h 7L2, fitting the cam -shapedchamber 13 of the pump-chamber, governing the sliding movement of theblades in the hub. The blades are cut away at the center to allow themto Other common forms of blades may be used without departing from myinvention. The hub in the present instance rests upon a plate B and hasits lower bearing in said plate, the upper bearing of the hub being inthe casing.

B is the cap-section, which is screwed into the end of the casing B andholds the plate B in position against the casing. The inletport b isformed in the plate B and also in the cap-section B as indicated in Fig.5. The inlet-port communicates with the chamber B at one side, while theoutlet-port 19 formed in the casing, communicates with the upper portionof the chamber at the opposite side. The cap-section B in the presentinstance has feet provided with spurs, which are forced into the bottomof the barrel, so as to rigidly hold the lower portion of the pump,raising the cap sufficiently off the bottom to allow the molasses toenter the inletopening. I prefer to screen the inlet-opening, so as tostrain the molasses as it enters the pump, preventing sticks and otherforeign matter entering the chamber and clogging the pump and barrel. Jis a screen within the cap section B for this purpose.

Above the pumping-chamber B in the present instance is thevalve-chamber, in which is a valve-plate I. In this valve-plate are oneor more seats itwo in the present instance for the valves I I. The seatsare tapered, and

the valves are tapered to correspond to the seats and have stems whichare guided by spiders carried by the plate, so that as the hub is turnedthe molasses will be forced up through the outlet-passage b into thevalvechamber and will pass the valves and enter the tube A.

The valve-plate I is supported by the casing B and is held in place by areducing-sleeve B which is threaded and is screwed into the casing B,and the lower portion of the stem A is also threaded and screwed intothe threaded portion of the reducing-sleeve. It will be understood,however, that in some instances this reducing-sleeve may be dispensedwith and the stem A screwed directly into the casing.

I will now describe the mechanism for registering the amount of molassespassing through the pump.

The bevel-pinion D, which is mounted in the head of the pump, has aneccentric-pin (1 on which is mounted a planet gear-wheel F. This wheelhas two sets of gear-teeth ff, and the two portions of the wheel are ofdifferent diameters. The teeth f mesh with teeth f on the fixed plate F,and the teeth f mesh with the internal teeth f 011 the wheel F connectedwith the dial-hand F", so that the dial-hand will only move a Very shortdistance for each revolution of the bevel-wheel D. In the presentinstance the dial-hand moves one sixty-fourth of a turn to one turn ofthe pump. The arrangement of the teeth and the relative diameters of thewheels will depend upon the quantities indicated upon the dial and thecapacity of the pump to lift a certain amount of molasses at eachrevolution.

It will be seen that the pump is so constructed that when it is wishedto remove the pumping-hub from the casing the cap and plate at the lowerend of the pump can be detached and the hub withdrawn, as it is notsecured to the shaft, but simply loosely coupled to it. The same is thecase with the driving-pinion D, mounted in the head of the pump, andthis can be readily removed by detaching the plate F. Moreover, theshaft being detachably connected to the hub and removable through thebottom of the tube said shaft can be readily removed without disturbingor necessitating the removal of the driving pinion or wheel D or thepacking.

The operation of the pump is as follows: On turning the handled bevelgear-wheel D the hub H and its blades are turned within the chamber B,and a given quantity of molasses will be forced up into the passage a inthe stem and in to the extension A The valve E being lifted, an amountof molasses will be forced out of the nozzle equivalent to the amountpumped,and simultaneously with this action of the pump the registeringmechanism will register the proper amount passing through the pump-inother words, the amount discharged from the pump.

By numerous experiments I have found that I can accurately register bythe apparatus shown and described the amount discharged by the pump, andI can so regulate the gearing that a certain number of turns will beequivalent to a pint of molasses discharged, and this number multipliedwill give the quarts and gallons, so that it will be seen that a retailgrocer, for whose use this pump is mainly intended, can readily measureinto any suitable vessel any quantity of molasses without having tofirst prime the pump or to provide a suitable measuring vessel toreceive the molasses from the pump.

By arranging the pumping elements at the lower end ofthe stem I dispensewith the need of priming the stem of the pump, and by locating themeasuring elements at the upper end I keep them clear of the molasses,preventing clogging and insuring accurate measurement.
